New this winter, wrestlers in the down position will continue competing as long as the supporting point(s) of either wrestler are inbounds. Previously, wrestling stopped when one competitor’s supporting point(s) went out of bounds.

This change creates a larger scoring area and is intended to reduce match stoppages that take place when action moves out of bounds. Supporting points include the parts of the body touching, or within, the wrestling area that bear the wrestler’s weight, other than those parts with which the wrestler is holding the opponent.

Also in wrestling this season, two-piece uniforms are allowed as well as the traditional singlet provided the two-piece uniform follows a list of requirements and does not extend below the knee. In addition, to enhance safety, three maneuvers were made illegal including a front flip or hurdle over an opponent who is in the standing position.

A few notable rules changes in basketball and swimming and diving also will be apparent this winter:

*In basketball, an official may now provide an official warning to the head coach—with that warning then recorded in the scorebook—or misconduct by the coach or other bench personnel, including players in and outside the coaching box. This warning is intended to make the message clear that there is misconduct and promote a change in behavior before a technical foul is called. However, a warning is not required prior to calling a technical foul if the misconduct is determined to be major.

*As with Lower Peninsula girls season in the fall, to promote safer take-offs during boys and Upper Peninsula girls swimming relays this winter, the second, third and fourth swimmers must have at least one foot in contact with the starting platform in front of the starting block wedge during take-off. Those second, third and fourths swimmers may not take off with both feet on top of the starting block wedge.

*Divers in the Lower Peninsula will need only four regular-season wins (instead of the previous five) to qualify for the Regional Diving Qualification Meet. A diver also may qualify if he places ahead of all divers from opposing schools in varsity competition in at least four meets, even if he does not finish ahead of his teammates. (This applies only in the Lower Peninsula where Regionals are conducted; Upper Peninsula divers qualify for Finals based on regular-season performance.)

The 2017-18 Winter campaign culminates with postseason tournaments beginning with the Upper Peninsula Girls and Boys Swimming & Diving Finals on Feb. 17, and wraps up with the Boys Basketball Finals on March 24. A reminder: The MHSAA Individual Wrestling Finals that are moving to Ford Field will be a two-day event this winter as opposed to a three-day event as in past seasons.
